You don’t realize how useful a black hole of a tote bag can be until you have one. It can turn what would normally be multiple trips from the car into a single haul. It’s especially handy if you live somewhere that charges for plastic bags, or you’re trying to cut down on single-use waste. It also pulls double duty beyond groceries, working just as well for flea markets, ballgames, laundry runs or beach days when you don’t want to schlepp everything over your shoulder.

This foldable, rolling grocery bag is incredibly spacious.

This Tcomake bag has three pockets, including one zippered outer one, and is made with a water-resistant polypropylene. The handles feature reinforced stitching to prevent tearing, while the four stainless steel wheels located at the bottom of the bag are made to swivel.

The brand sells three sizes of bags — small, medium and large — each with its own weight limits. The small bag measures 14.4 x 12.5 x 19 inches and can carry 22 pounds max. The medium measures 16.5 x 14 x 23.5 inces, with a max load of 46 pounds. The large has a max weight limit of 76 pounds and measures 20 x 16 x 27 inches.

Note that while all colors of the medium bags are on sale, only select colors of the small and large sizes are currently discounted.
